BlinkyTile doesn't reset when closing patternpaint

[cibomahto]

To reproduce:

1. Run patternpaint, select 'blinkytile' from welcome screen
2. connect lightbuddy+blinkytile to computer
3. After patternpaint detects and starts controlling blinkytile, close patternpaint
4. BlinkyTile should start playing back it's original pattern

BlinkyTile needs a call to 'reloadanimations' in order to re-start it's pattern engine. With BlinkyTape, this is handled with a call to reset(). Either implement this in reset() or make a new function in BlinkyControler() to restart animation playback.
